State of New York, have invented new and useful Improvements in Winding Devices, of f panying drawings form a part in which V which the following is a specification.

This invention relates to winding devicesfor tape-controllers, and is a division of my application for Letters Patent on an electric sign, No. 843,267, Series of 1900.

A tape of. this class, whether it be designed to control electric current, current air, rays of light, heat, magnetism or other energy, must travel in a fixed directlon during the performance of its work. 'l .o accomplish this,the ends of the tape are yoined together so as to form an endless band which is passed around rollers or similar devices. Such an arrangement, however, is impractical for any but extremely short tapes. ln longer tapes, one end is attached to a reel and the reel rotated until the opposite end of the tape is reached. lhe tape may then be wound backward until the original end again appears, and the former operation repeated, butwork is interrupted and time lost during this backward movement of the j tape. i 7

An object of the present invention is to provide a device of this class that Will permit of the movement in the desired direotion without interruption of a tape of great length.

An important object is to provide a device that will engage and wind any part of a traveling tape into a coil. i

Another broad object is to provide a'reel on and 0d which thetape may he wound during its travel in one and the same direc- Another object is to causing the rewinding o the tape when its hold on the reel has relaxed, or in other words, when the reel is free of tape, whereby no additionalperforations or the like on the with the steady travel of the tape, so that the tape, or portions thereof will be wound on both reels, successively.

With these and other objects in view, the nvention consists in a device ofthe, class specified, constructed and operating as herematter described and claimed.

Theinvention is fully disclosed the following specification, of which the accom- Figure l is a plan view of the various parts of the device with portions broken away;

Fig. 2 a section on the line 22 of Fig. 1;

V Fig. 3 an enlarged section on the line 3-3 of Fig. 1 i

' Fig.4 a section on the line M of Fig.3; Fig. 5 a view similar to Fig l ut showing only" a part of the construction and showing the same in section; and,

. Fig. 6 a diagrammatic view of the electric circuits employed in connection with thedevice.

Mounted in a support a (Fig. 2) is a. tubular shaft 27 on which is loosely mounted a .bar' 2' in oppositeiends of which are mounted shafts i on the outer ends of which are rotatably mounted reels a" and i.

- Wound on the reel '5" is an endless tape d (Fig. 1) which is also passed around three -guide wheeled? and around a driving wheel 'd which may be provided with teeth d troducing the brush 6 and the contact pointsa in an electric circuit and by providing the tape d"- with apertures or electrically conducting parts current will flow from the brush 1) to such of the contact points a" as will be facing'an aperture or a conducting partof the tape ol", which current may be utilized for any purpose desired. Qllhis illus V trates one of the uses'for which tape-controllers are adapted.

Rotatably mounted on the tubular shaft 1' between the support a and thebar itis a gear or toothed wheel 1; having a hub portlon provlded with a groove 71' in which is placed a belt i which is also passed around a pulley j secured to a shaft 3' supported in the support a, and secured to the shaft 1' V adjacent to the pulleyj is another pulley j around which is passed another belt 7* provided with a smallerhead n". Pivoted in which is also passed around a pulley of a motor not shown. The shaft 1' may also be provided with a pulley (not shown) to whiclii the tape-driving wheel (5 may be belte Secured to the outer end of the tubular shaft 2' is a friction disk 70 having a metal facing I2 ('Fig. 6), and secured to the shaft 6 between the disk is and the bar 2' is a con magnet is its armature m having a spring m adapted to hold the free end of said armature in connection with stops m secured to the support a as shown in Fig. 2, thereby locking the bar it except when the magnet m is energized, in which instance the armature m? will engage the teeth of the wheel 2' to rotate the bar 2' as will be hereinafter described, and secured to the bar 2' at m is a brush m adapted to engage a metal ring m secured to the friction disk is and having electrical connection with the sheet metal facing 7c? thereof as shown at. m in Fig. 6.

The reels 2' and 2' are exactly alike and consists each of a central hub portion n' approximately semi-spherical in cross section, as shown in Fig. 5, and circular side plate members n which form guides for the tape d when wound thereon, and the members n are provided with circular apertures n.

Pivoted to the outer side of said 'reel as shown at n is a plate 11, forming a 'part of the mechanism for holding said tapeto said reel and having at one end a grab head a WhlCh 1s adapted to operate in one of the apertures n and the other end of the plate n is the side edge portions of the plate adjacent to the head n are'operating rods n which pass through and operate in apertures n in the hub portion n of the reel and are connected with a plate n pivoted to the back of the reel as shown at a and the plate n is also provided with a circu- .lar head a" similar to thehead n of the plate 12 I The heads n and n of the plates n and n extend inwardly to form circular members around which'the tape loops after said heads have closed to grab said, tape as-hereinafter described. 7

One corner of the semi-circular hub portionn is provided with a recess n in which is plvoted an L shaped contact finger o, the

head 0 of which is adapted to engage the sheet metal facing 10 on the disk and the finger 0 is held in engagement with said facmg by means of a sprmg 0 as shown 1n Fig. 4:.

The back of the reel 15 also provided with a circular flange or run a, and mounted on the shaft j is a friction wheel a adapted to engage said rim portion and rotate said reel in the operation of the device, as shown in Fig. 2.

Mounted adjacent to and above the reels i and i is an oblong guide frame 0 the lower surface of which is cut out as shown at 0 forming grooves 0 shown in dotted lines in Fig. 1, and the heads a of the plates a are adapted to operate in the grooves 0 of the frame 0.

Secured to the back of thehub portion of the reels 71* and i and within the rim portion a are brushes 0 and 0 which bear on the shafts i and connected with said brushes and the ,finger 0 are wires 72 and p and connected with the brush m is a wire 39 which is coiled around the magnet m, and connected to the brush is by the wire 39, and secured to the shaft 2' is a wire p which is connected with a battery p", and a wire 19' is connected with said battery and with the contact disk I2 and connected with the brush k is a wire p which is also connected with both the shafts i and connected with the brush 7: is a wire p which is connected to a contact 12 adapted to engage the armature m and another contact 72 which also engages said armature is provided with a wire 19 which is connected with the wire p The above wiring is shown in Fig. 6 and the object thereof is to control the unwinding and rewinding of the tape off and on the reels 2' and i and in Fig. 5 I have indieatedthe direction of travel of the tape and if considered in connection with Fig. 1, it will be seen that the reels i and i have changed their position by reason of the fact that the tape on the reel i had been completely unwound and the finger 0 freed so as to make contact with the metal facing and this contact completes the circuit through the wires to the battery and mag nets. This draws the armature m in engagement with the toothed wheel 2' and holds it there, circuit having also been completed across the contacts 39 and 1), until the circuit is broken, and the wheel 11 which is continually rotating will carry with it the bar '2' which supports the reels 2' andi; V

In the above operation of rotating the bar 2' with its connected parts the head a of the reel 71 engages the grooves 0 of the guide frame 0 and this depresses the plate fits on said reel which depression throws the circular heads a and a outward as indicated in dotted lines in Fig. 3, and this permits the free exit of the tape at", and by means of the construction of the grooves in the frame 0*, the heads 41. and n will retain the said position until the tape has again entered the reel between the hub portion a and the said heads after which the head a leaves the frame 0 and the plates a and 71 assume the position shown in Fig. 3, the heads at and n now being in position to grab the tape. The bar 71 will continue its semi-revolution until the brush is has reached the insulated spot is on the disk is.

The rotation of the bar 2' will now have stopped due to the breaking of the circuit by the said insulated spot is", for the magnet is denergized, and the armature m? will be withdrawn from the wheel 2' and drawn against one of the stops m, by the action of the spring m The reel i will now be rotated by means of the friction wheel 72. and the tape d in thebeginning of this operation 'will assume the position shown in Fig. 5, in which position the tape is placed around the heads a and n of the reel 71 and about to be wound thereon, and since there are no sharp corners for the tape to encounter, nor frictional or any other injurious contact between said reel'and the tape in the beginning or any other part of this operation, the transfer of the tape from one reel to the other will be accomplished without injury to said tape. In this position or in the beginning of the said winding, the finger 0 has been forced inwardly by said tape and the head 0 thereof clears the facing k of the disk k. I

In the above operation at unwinding and rewinding' the endless'tape, the same is continously traveling in the direction of the arrows (Fig. 5) except between the reels, where it will travel in the opposite direction during the unwinding of one reel and rewinding of the other, and if said arrows were to travel with the tape, they would point backward upon reaching the said location between the reels, aswill be understood and after the full reel leaves the friction wheel n its rim portion n 4 will roll around the friction diskk and will cause the'reel to continue its rotation and thereby prevent slack in the tape during the changing of the reels. The friction disk also revents the too free rotation of the reel while in its un-' winding position. I may also employ spring- I operated rollers 1' to make doubly sure thatto exhibit for a predetermined length of time.
